Dec 22, 2020 The easiest and quickest way to clean a rotary evaporator is to simply flush the machine with acetone (or another solvent of your choice). While this is not the most thorough cleaning method, it is ideal for situations where time is limited. To flush a rotary evaporator with acetone, fill up a small two-neck flask around halfway with acetone.
